PESD0402MS05-MS

MSKSEMI · ESD And Surge Protection (TVS/ESD) · 0402

PESD0402MS05-MS from MSKSEMI, in a 0402. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 IO1 passive One terminal of the bi-directional single-line ESD protection diode, rated for 5 V continuous operating voltage and 8 kV contact / 15 kV air IEC 61000-4-2 discharge.
2 IO2 passive Second terminal of the bi-directional single-line ESD protection diode, interchangeable with the other terminal, with 0.05 pF typical capacitance.

  • Symbol: PESD0402MS05-MS
  • Footprint: Resistor_SMD:R_0402_1005Metric
  • 3D model: 0402 (KiCad packages3D, STEP)
  • 3D model files: pesd0402ms05-ms-etched.step / pesd0402ms05-ms-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); pesd0402ms05-ms.step / pesd0402ms05-ms.glb are the bare package body.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:

  • Datasheet: MSKSEMI datasheet (6 pp, sha256 33ed6b0851a73014, retrieved 2026-09-29, tier: lcsc)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
